This appears to be horse tack from a horse named Mt. Fuji in Minami-Furukawa, Ehime Prefecture. I purchased it at an antique shop in Matsuyama. The red pieces are a face cover, chest cover, and crupper, along with decorations, while the indigo pieces are a chest cover and crupper. As these are old items, their practicality is questionable. Suitable for decorating a dummy horse, etc. Since it bears the name of Tomisuyama, famous for its azaleas, it is likely that this was a good horse.
